Perspective of Curves

This drawing was done in 20 minutes and is a study of the perspective of curves. The closer to the centre of the drawing the curves get, the more straight they get, vice versa the further away the curves get, the longer they get. The horizon line of the piece is midway through the windows along the bottom. The tops of buildings at either side of the curves should represent the vanishing points, though the one on the right has an error in that it does not correspond to its counterpart. There are errors with this piece, mostly with shading, the most prevalent of which is the curves of the atrium, the light would not not create shadows like those seen in the piece, and should instead show a gradual thinning from the right to the left. 

For the second drawing, black and brown conti crayons along with a graphite stick  have been used. From a different vantage point, the focal point is instead not the the curves themselves, but instead the tree in the foreground. Rather than be a highly detailed object, the tree, and in turn the piece its self becomes very impressionistic, as opposed to the other drawing. The mixed colours allows for a great contrast which allows the tree to stand out greatly and give the piece depth of field. The atrium which has the curves on it has become a backdrop, and the horizon line is represented by the bar at the bottom of the curves themselves. It could be said that there is an implied line down the curves of the right hand side of the atrium, and then down the trunk of the tree itself.
